What would you call a solution that contains 300 g/l nacl at 25 c
Lady bird [3.3K]

The solution will be called as saturated solutions.

<h3>What are saturated solutions?</h3>

A solution in which all of the solvent has been dissolved. Any additional solute will form crystals on the bottom of the container.

An example can include a solution that contains 300 g/l NaCl at 25 degree Celsius.

Thus, the solution will be called as saturated solution.

A solution has an initial concentration of 0.0100 m hclo (ka = 3.5×10−8 ) and 0.0300 m naclo. what is the ph after the addition
In-s [12.5K]
When [HClO]= 0.01 M  & [ClO]^- = 0.03M & NaOH = 0.003 mol and
 Ka = 3.5 x 10^-8 
and the equation is:
            HClO + NaOH → Na^+  + ClO^-
initial     0.01     0.003        0.03     0.03
            -0.003 - 0.003      +0.003  + 0.003
Final    0.007        0             0.033      0.033

We can get the PH from this formula:
PH = Pka + ㏒[conjugent base/weak acid]
PH = -㏒Ka + ㏒[Na]/[HClO]
      = - ㏒ 3.5x10^-8 + ㏒(0.033/0.007)
     = 8.13

Which of the following has the largest electronegativity? AI, Cu, S, or O?
puteri [66]

Answer:

O(Oxygen)

Explanation:

Oxygen or O among the given options has the highest electronegativity of 3.5 as compared to 2.4 of sulfur. Thus, there is a lesser attraction in the bonds of Sulfur. <u>The other two elements Al(Aluminium) and Cu are less electronegative than Sulfur and Oxygen as they are metals and possess electropositivity while the latter displays more electronegativity due to being non-metals</u>. Hence, Oxygen is the answer.
